I have been on Tramadol SR now for 14 months. I was started off on 300mg a day and because I was feeling good and the pain in my back was under control I reduced the dose to 150mg a day taken in the morning, this is good as the pain I get at times is minimal. The symptoms I have is the hair loss that is concerning me mostly. I do get dry mouth and night sweats as well. I also have type 2 diabetes.
